BOTTLE CLOSURE.

Specification of Letters Patent.

Application filed September is, 1920. Serial No. 416,689.

useful- Improvements in'Bottle Closures, of

which the following is a description reference being had to theaccompanying drawings, which are a part of this specification.

This invention relates to certain new and useful improvements inclosures for containers, and refers more particularly to means forhermetically sealing a bottle.

It is oneot the objects of this invention 'toprovide a closure for abottle so designed that the same may be readily attached thereto tohermetically seal the same, and at the same time be capable of easyremoval.

Another-object of this invention is to provide a bottle closure forhermetically sealing a bottle .and one which capable oi? use anunlimited number of times.

It is a further object of this invention to provide a bottle closurewhich is formed of but a few parts, all of: which are capable of beingstamped from sheet metal, whereby the same may be produced at acomparatively low cost.

A still further object of this invention is to provide a bottle closureso constructed and designed as to maintain its hermetic seal with thebottle mouth irrespective of the pressure within the bottle.

With the above and other objects in view which will appear as thedescription pro ceeds, my invention resides in the novel construction,coinbination and arrangement of parts substantially as hereinafterdescribed and more particularly defined by the appended claims, it beingunderstood that such changes in the precise embodiment of thehereindisclosed invention may be made as come within the scope of theclaims.

In the accompanying drawing, 1 have illustrated one complete example oithe physical embodiment of my invention constructed according to thebest mode l have so far devised for the practical application oi theprinciples thereof, and in which:

Figure 1 is a view of a. portion of a bottle equipped with my ii'uprovedclosure, parts of the closure being brokenaway and in section;

Figure 2 is a view similar to Figure 1, a portion of the bottle beingbroken away and in section and the improved closure being shown insection; and

Figure 3 is a perspective View of the bottle engaging retainer or clampmember detached.

Numerous devices have been designed for hermetically sealing bottles,but they have all been open to objection in that they either requiredexpensive machinery to apply them .or else, while capable ofhermetically sealing the'bottle, would not hold when subjectedtopressure from within.

Hence my improved closure is designed to be capable of instantattachment without the need of any machinery whatsoever and capable ofwithstanding any degree of pressure from within the bottle. Thisinvention consists of a bottle engaging retainer or clamp member 5,awasher 6 0i rubber or the like which is carried by the member 5 forengagementover the mouth 7 of the bottle 8, a guard or cap 9 forenclosing the member 5 and washer 6, and means for causing the retaineror clamp member to bind against the bottle neck and force the washer (Sin to engagement with the rim 10 surrounding the mouth of the bottle.

The retainer clamp member 5 is formed from a single piece of materialand has a, central disc or circular portion 11 provided with a pluralityof depending prongs 12, the ends of which are directed inwardly, as at13, then outwardly, as at 1 1, for the purpose to be. later described.The central portion 11 of the member 5 is raised or bulged, as at 15,and in the recess formed by said raised portion, the head 16 oi a bolt17 is positioned. The shank of the bolt 17 adjacent its head ispreferably squared and the opening in the bulged portion 15 throughwhich the shank passes is correspondingly shaped to prevent the rotationof the bolt when its winged nut 18 is being placed thereon or removedtherefrom.

The washer 6 is placed against the underside of the disc 11 and is heldin position by the prongs 12, and also serves to retain the bolt 17 inposition, see Figure 2. In practice, the member 5 is placed over themouth of the bottle, when prongs 12 will spring over the rib 10 and theshoulders or inbent portions 18 will engage behind the rib 10. Withtheparts in this position, the cap or guard 9 is placed thereover withthe bolt 17 projectin through an aperture in Patented Mar. '7, 1922.

edge of the cap member will force the prongs inwardly and thus firmlysecure the closure of the bottle against removal and hermetically sealthe same by firmly pressing the washer 6 against the bottle mouth.

When it is desired to remove the closure, the nut 18 is unscrewed, whenthe capor guard 9 Will be disengaged from the prongs l4 and the entireclosure may be disengaged by springing the shoulders 13 over the rib 10.From the foregoing description taken in connectionwith the accompanyingdrawing, itwill be at once apparent to those skilled in the art to whichan invention of this character appertains that I provide an improvedform of bottle closure for positively hermetically sealing a bottle, andwhich may be readily attached without the aid of any machiner whatsoeverand which may be used an unlimited number of times.

lVhat I claim as my invention is:

1. A device of the class described, comprising a retainer provided withdepending prongs engageable over the top of a bottle,

1 a washer carried by the retainer for closing the mouth of the bottle,a cap positioned above the retainer, and means for drawing the retainertowards the cap to press the prongs into engagement With the bottle andform an air tight joint between the washer resilient engagement with thebottle and" secure the device thereon.

3. A bottle closure, comprising a retainer having depending prongsengageable over the top of a bottle, a sealing washer carried by theretainer between said prongs, acap member extending over said retainerand engaging the pron-gs a bolt connected to the retainer and extendingthrough the cap member, and a nut threaded on the bolt and positioned ontop of the cap member for a
